UNITED STATES LEONARD KING, OF LUTON, ENGLAND.

AUTOMATIC SPRINKLER-BROOM.

Application filed December 29, 1919.

To all whom it may concern.

Be it known that I, LEONARD KING, a sub ject of the King of Englandresiding at Luton, Bedfordshire, in the kingdom of England, haveinvented new and useful. Automatic Sprinkler-Brooms, of which thefollowing is a specification.

This invention relates to sprinkler brooms carrying water tanks, and myobject is to provide a manually operated broom of this character inwhich an air pump causes an intermittent water spray to be deliveredwell ahead of the broom; a feature of the invention beingthe automaticoperation of said pump by a pivoted cranked lever touching the ground orfloor and receiving an impetus at each forward sweeping action of thebroom.

I attain my object by the combination of the means which I will nowdescribe with reference to the annexed drawings in which:

Figures 1 and 2 are a front and side elevation respectively of thebroom; Figs. 3 and 4: show to a larger scale a rear elevation and planrespectively of the middle portion of the broom. I

Fig. 5 shows a sectional view through Fig. at showing the division ofthe tanks.

is the broom having three communicat ing tanks Z) for holding liquid,and c is the air pump provided with a piston or plunger 0 fordischarging the liquid from the tank Z) through a nozzled. The tank isdivided into three compartments b b 5 and the pump or the centralcompartment Z2 is fitted with non-return valves 0, e which allow theliquid to flow into the pump. Filling orifices b are also provided forfilling or replenishing the compartments 6 and b3 as and when required.

The rod 0 of the plunger 0 is connected Specification of Letters Patent.

to an arm or lever 7 which is pivoted at f and at its other extremityforms a forked member 9 carryinga wheel or roller g for making contactwith the floor or surface over which the broom is moved, the arrangementbeing such that as the handle or stail a of the broom is presseddownward in the action of sweeping, the wheel or roller 9 is forcedrearward on the floor to cause the plunger of the pump to descend anddischarge a supply of liquid through pin-holes in the nozzle (Z. Thereturn movement of the plunger 0 is effected by a spring or springs cwhich come into action when the pressure causing the wheel or roller gto be forced into contact with the floor is removed.

Supporting wheels 72 are also yieldingly mounted one at each end of thebroom to support or take the weight off the bristles of the broom, thus,when pressure is brought to bear on the broom in the act of sweeping,the resistance of the springs 2/ will be overcome to permit the bristlesbeing brought into close contact with the floor, while the roller andforked member 9 will cause the pump to be operated to discharge liquidfrom the compartment 6 of the tank 5.

I claim:

A manually operated broom means provided on the broom for carryingwater, a force pump carried by the broom, a pivoted cranked operatinglever for said pump with the lower end near the surface being cleaned,

a contact roller carried by said lever near' the lower part a spray headat the front of the broom and means establishing communication betweensaid head and the pump, and yielding supporting wheels at the ends ofthe broom, as herein described.
